Disconnection & Reconnection: The NSW Level 2 Guide

What Disconnection and Reconnection Means

A network disconnection physically isolates your property from the grid at the network side — at the pole, pillar or service fuse — so there is no live supply entering the premises. A reconnection restores that supply once the reason for the disconnection has been dealt with.

This is different from simply switching off your main switch, which leaves the network side live up to your meter. A true disconnection removes the network supply entirely, which is what makes it safe for demolition, major switchboard work or relocating a service. Only a Level 2 ASP can disconnect and reconnect at the network, because it involves working on distributor-owned assets.

Common Reasons for a Disconnection

Demolition is the most common. Before a building is knocked down, the supply must be safely disconnected and, usually, the service line and meter removed so demolition crews aren't working around live conductors. This is a mandatory step and councils and demolition contractors will ask for evidence it has been done by an accredited person.

Major electrical works are another. Upgrading a switchboard, replacing consumer mains or moving a metering panel often requires the supply to be dead while the work is carried out, then re-energised and tested afterwards. Relocating a service — moving the connection point to a new part of the property, or converting overhead to underground — also needs a disconnect and reconnect.

Emergencies make up the rest. A fire, a flood, storm damage or a dangerous fault can all require the supply to be isolated fast to make the site safe. Sydney Power Group's on-site within 60 minutes response is built for exactly these situations.

Temporary vs Permanent Disconnection

A temporary disconnection is used when power will be restored — for example, during a switchboard upgrade or renovation. The supply is isolated, the work is done, and the ASP reconnects and re-energises once everything is compliant and tested.

A permanent disconnection (sometimes called an abolishment) is used when the supply will not be restored — typically before demolition or when a service is being permanently removed. Here the service line and meter are removed and the account is closed with the retailer. The distinction matters because it changes the applications lodged and the way the network handles the request.

How the Process Works

The process begins with the right application to your distributor and, where relevant, your retailer — the type depends on whether the disconnection is temporary or permanent, and whether metering is being removed. Your ASP lodges these and coordinates the timing so the outage lands when it suits your project.

On the day, the ASP isolates the supply at the network, proves it dead, and carries out or enables the works. For a reconnection, they re-terminate the connection, test polarity and correct operation, and energise the supply. Because Sydney Power Group is accredited across Ausgrid, Endeavour Energy and Essential Energy, the same team can handle disconnect and reconnect anywhere in the greater Sydney and NSW network areas.

Why It Must Be a Level 2 ASP

The connection point — the pole, pillar or service fuse — is network property. Working on it without accreditation is illegal under NSW rules and exposes you and others to the risk of contact with live conductors. Retailers and distributors will not recognise a disconnection performed by anyone other than an accredited person.

Using a Level 2 ASP means the paperwork is correct, the outage is coordinated, the work is safe, and the reconnection is properly tested and recorded — so your project isn't held up by a rejected application or a failed re-energisation.
